Neural Network Loss Function: Mean (absolute) Cubic Error

Hello,
for my neural network, it's very important to not have a high error-range, i.e. a higher mean-error is better than a higher error-range.
That's why I'd like to implement a different loss function. My network has a regressionLayer Output which computes loss based on mean squared error. To increase the weight of errors that lie further away, I'd like to change that into a mean cubic error.
The standard loss function of the regression Layer is
and I'd like to perform a tiny change to
or alternatively
.

Is that possible in a not so complicated way?
Thank you for your help in advance,
Best regards

You want the error to be negative if t_i < y_i ?
This won't work: The loss function should always be non-negative.
